The diameter of the HGA7T antennae seem smaller than the existing ones. If the crossbar fits over the TNC connectors to ensure the high gain antennae fit, there doesnt seem to be room for the connectors to the modem etc to fit in between the TNC conncecors. My problem is that if I open the shrinkwrap and it turns out the antennae won't fit then Amazon won't take the package back, so I need to be sure!

The antennas screw on the back, replacing the existing one. Then the crossbar fits over the TOP of the antennas and there is a section of the antennas was made fatter to accomodate the crossbar fitting snuggly.

Thanks a lot! However, having now fitted the high gain antennas, I find they do not enable the signal to carry to my son's room upstairs, which is only about 20 feet as the crow flies. Is there anything else I can do to boost the range?

The way I understand these type of antennas is that it tends to flatten out the signal(think of a dougnut being squished so it's an oval instead of round), thus while something on the same level as the router with the high gain antennas may be able to work farther away, things above and below the router may actually receive a worse signal.

I had the same issue with those antennas. My router(WRT54GS) is one floor down and across the house from where I sometimes use my laptop. What I did was buy another router(WRT54G converted to a GS) and put it upstairs, within an ok signal range of my downstairs router and then ran it in WDS-AP mode to use it as a repeater. Now, no matter where I am in the house I get an excellent signal.
